AI Technical Summary
Technical Problem
Existing display devices suffer from high external light reflectance due to the use of metal materials in the cathode, which degrades reflective visibility and contrast ratio, and the use of thick polarization plates or coated polarization films leads to increased thickness and reduced display quality.
Method used
A display device structure is designed with a color filter layer disposed on an encapsulation layer, incorporating a bank with varying heights in non-emission areas to offset external light, reducing reflectance and power consumption without a polarization plate.
Benefits of technology
The solution lowers external light reflectance, allows for low-power driving, increases lifespan, and enhances luminous efficiency by eliminating the need for a polarization plate.

Abstract
A display device includes a first electrode disposed on the substrate. The display device further includes a bank disposed on an edge of the first electrode and includes a first part and a second part that encloses an area in which the first part is disposed. The display device further includes an organic layer disposed in a part of a top surface of the first electrode. The display device further includes a second electrode disposed on the organic layer and the bank. The display device further includes an encapsulation layer disposed on the second electrode. The display device further includes a color filter layer disposed on the encapsulation layer and that overlaps the organic layer and the first part. The display device further includes a black matrix disposed on the encapsulation layer and that overlaps the second part.
